Nah, vertical green bar is outside my horizontal living-range.Dan123:

I’m a popsicle that the local wildlife likes to lick on, at that point.

Indeed. The point is the next generation is going to overall look a lot more like Matt than you.

The cold would kill the food supply for Matt also.

Not the part that’s also adapted to better survive cold. Like the dogs we discussed - your boxer and pug are both going to die. But your german shepherd stands a chance (which is, in itself, another example of evolution being carried out).Vonsalza:

He can go hunt one

Here I’ve adjusted it to be more inclusive. Of note mVitus has a mutation that allows him to survive in a larger range of temperatures than the rest of us, and I have a mutation that limits me, I might not even survive an otherwise normal cold snap.
The point for Techno2000 about the pressures causing the evolution is that it’s reversed. All these spectrums exist FIRST. mVitus may not benefit from his mutation AT ALL if the temperature range stays within the blue norm, but if it drops to the orange line Volsalza and I are dead.

Dan is giving you an excellent presentation of the point in a targeted way you’re likely to seldom enjoy again, Techno. I’d consider it.

I though you said the ice age started overnight.Where did the millions of years that evolution needs to evolve these adaptations come from ?

They already have them through genetic variation.Vonsalza:

It’s why someone people are better athletes than others, among a million other things. It’s why you find coyotes all over the United States - they have a wide range in which they can survive. These are attributes that these things already have. Right now.

If two cars are stranded in a blizzard the driver who already has the survival gear in their trunk is the one more likely to survive.
That person is then more likely to raise kids who keep survival gear in their trunk.

Perhaps. If it did then Matt would die out also. That is definitely possible though we’d probably see lots of extinct species in the fossil record if that was something that happened from time to time and … oh right.

The goalpost for this cold climate change scenario keeps moving.It’s now has become the perfect environmental pressure that works in perfect harmony with evolution.The perfect temperature allowing for just the right amount of survival and reproduction.

Evolution doesn’t work that way, it takes millions of years to evolve the survival gear… that’s too late for the driver.

We agree. He’d have to be better prepared BEFORE the change.

By the way, is the picture working on your end? I keep getting an error when I try viewing it.
And Techno, I don’t see anything that’s lining up perfectly. I think you’re assuming that the goal was to create harrier humans. When really it’s just the way the environment is playing out and, by chance, harrier humans are doing better.

Hardly. Here’s 3 charts, the top shows the current population of our made up species, then below I’ve considered two possible scenarios, a cold snap and a heat wave, and how they would affect the population. The cold snap and heat wave would affect creatures based on their existing traits.

Works for me but I uploaded the one above this post as a jpg instead of png just in case that helps you see it.

No, you’re not understanding.Dan123:
Evolution doesn’t work that way, it takes millions of years to evolve the survival gear… that’s too late for the driver.
In 65.2 degree F Kentucky, both long-hair and short-hair dogs can survive outside year-round (even though the short-hairs will need to find some place to den-up during brief cold snaps).
If a mini-ice age broke out, the short-hairs would all die because Kentucky winters already take them to their survival limits. But the long-hair dogs already possess the survival gear/adaptations needed to survive the change.
Dan’s doing a better job of this than me. All yours, Dan.

Thanks for the effort. Unfortunately Discourse seems to hate me right now. But I assume the orange line is near where the green line was?
